|Enhanced Firing Modes - "Various modes which add shots, or perform
in ways more complex than semi-auto and full-automatic modes of fire. Common
advanced modes will fire multiple shots per trigger pull, but only when
the trigger is being pulled at least as fast as a minimum number of times
|Expansion Chamber - "A chamber - often screwed into a vertical ASA
on a paintgun - which is design to use gravity to physically prevent liquid
CO2 from entering the paintgun's valve, and also to allow the gaseous CO2
to absorb ambient heat, stabilizing its pressure."
|eye - "A combination of a light (usually infrared) emitter and detector
used to electronically detect the presence or absence of a paintball. Eyes
are commonly used in electronic loaders, and in electronic paintguns to
prevent the paintgun from firing before a ball has completely entered the
|Fanning - Rapid firing a paintgun by holding it with one hand while
rapidly activating the trigger with the other.
|Fiber Wrapped - "Many 3,000 psi and 4,500 psi rated compressed air
tanks consist of an aluminum tank that is wrapped with glass or carbon
fibers, sealed in resin for added strength."
|Field - "The area in which a game of paintball is played - either the
specific site and boundaries of a game, or the general area in which people
meet to play."
|Fill - The paint which fills a paintball.
|Fill Station - The equipment used to refill a CO2 or HPA tank.
|Flag Hang - Hanging a flag at its goal station during a flag based
paintball game. In center-flag and two-flag format games a flag hang ends
the game. In repeating goal game formats like X-Ball a flag hang resets
the field to start the play for the next point.
|Flag Pull - Pulling a flag from its starting station during a flag
based paintball game.
|Flag Station - "A position either where a flag is at the start of the
game, or where it must be taken to end the game or earn points."
|Football - "A center-flag paintball game, or two pods taped together
and carried on to the field, so that a player can reload their hopper twice
before needing to pull a pod from their pack."
|Force Feed - "Force-Feed loaders use spring pressure, pressure from
a motor, air pressure, some other source or combination to actively push
paintballs from the loader into the paintgun."
|FPO - "Field Paint Only - Many commercial paintball fields, tournaments
and paintball events only allow the use of paint that is bought at the
field. This is a part of their business plan, and very similar to the way
restaurants and theatres only allow food purchased on site to be consumed
on the there."
|FPS - "Feet Per Second - the standard unit of measurement for the velocity
of paintballs. Three-hundred feet per second is considered by the paintball
injury to be the maximum safe velocity for paintball impacts. To provide
a margin of safety, most paintball fields restrict velocity to 285 feet
per second measured at the muzzle of the paintgun. For night or indoor
play, night games, or younger players, 250 feet per second is a common
|Freight Train - "Lining up multiple players to charge down the field
all in a row, so that the referees are focusing on the front player, while
the next players in line are shooting out their opposition - freight training
is used to distract the referees from the fact that one or more of the
players in the train are continuing to play after being hit."
|Front Player - "A player who pushes far down the field during a game,
relying on guidance and cover from team-mates behind them. Front players
are usually of smaller stature and faster speed than their team-mates,
and typically carry less paint."
|FSDO - "First Shot Drop Off - Some paintgun designs - especially spool
valve designs, are susceptible to a situation where the valve can stick
if it sits for an extended period of time between shots. This leads to
the first shot of a string having a lower velocity than the rest. Some
electronic paintguns feature anti-FSDO technology, in which they activate
the valve for a longer period of time (increased dwell) on any shot that
occurs after a wait of 10 seconds to a minute or two."
|Full Auto - A mode of fire in which a paintgun fires repeatedly while
its trigger is being held back.
|Gat - "A 1920s gangster slang for a pistol - you know, a heater, a
piece, a rod, a ventilator."
|Goggle - "Paintball goggles protect the eyes from accidental impact
from a paintball. Goggles which meet the ASTM standards for paintball use
are a critical component for player safety - shop goggles, ski goggles,
or any other goggles are not designed for paintball use and do not provide
the necessary protection. "
|Gravity Feed - "Gravity fed loaders, even though they may have motors,
agitators, or other more advanced components, rely on gravity to draw paintballs
from the loader into the paintgun."
|Grill - "A players facemask - especially when it is hit - as in ""He
was all up in my grill,"" or ""Oohh! He got grilled!"""
|Guppy - A pod.
|Hammer - A mass of metal in a paintgun which strikes and opens a valve
when driven forward either by a pneumatic ram or the paintgun's mainspring.
|Harness - "A pack which usually straps to a player's waist to carry
pods of paint. Pods are usually fitted into pockets or elastic loops on
the back of the player's waist. During tournament play, empty pods are
usually discarded on the field after they are pulled and emptied into the
hopper. Expended pods are picked up after the game is over."
|Hex Wrench - See Allen Wrench
|Hopper - A loader which is mounted on top of a paintball gun and holds
paintball. Typical hoppers hold about 180 paintballs.
|Hose - "As a noun, hose refers to the hoses to connect gas fittings,
as a verb it refers to firing a lot of paintballs at someone, or literally
hosing them down with paint."
|HPA - "High Pressure Air - Compressed air stored at typically 3,000
psi or 4,500 psi to power paintguns. HPA tanks are usually fitted with
a regulator on the tank, to reduce output gas pressure to 400 (low output)
or 800 (high output) psi to power paintguns. Adjustable HPA systems have
an output pressure which can be adjusted. Preset HPA systems are set to
output low or high, and most models can screw into an ASA simply replacing
a CO2 tank. Typical home, or workshop air compressors do not come close
to generating the pressures needed to refill HPA systems. "
|Hydrostatic Testing - "In order to comply with DOT regulations the
tanks used to store CO2 and compressed air must be hydrostatically tested
(pressurized in a tank of water to measure how much they expand) by the
manufacturer. Larger diameter CO2 tanks, and all compressed air tanks must
be hydrostatically tested on a regular schedule (3 or 5 years, depending
on model) to remain in service."
|Hyperball - "A brand name of concept field, though the term is usually
used generically to refer to any concept field in which the bunkers are
made from corrugated sewer pipe."
|Kill - To eliminate an opposing player by marking them with a paintball
that strikes and breaks open on them - considered politically incorrect
by some players.
|Kit - "Accessories to go with a paintgun, such as hopper, pods, harness,
etc. This term is typically used by English, rather than American players."
|Laydown - A cylindrical inflatable bunker laying on its side usually
large enough for a crouching player to take cover behind.
|LCD - Liquid Crystal Display - LCDs are used to display text or icon
information from electronic components. They are typically grey in color
with black letters and visible in direct light. They can also be illuminated
to be red in dim light.
|LED - "Light Emitting Diode - a small, solid state light. LEDs can
also be arranged into displays to display text information, though these
are often difficult to see in bright sunlight."
|Live Player - A player who has not been eliminated when the game ends.
|Loader - "A device which attaches to a paintgun. The loader holds,
and feeds the paintballs to the paintgun. Loaders can rely on gravity alone
or include an agitator to prevent paint jams, or a force-feed system to
actively drive the paintballs into the paintgun. Most loader designs involve
a hopper that sits on top of the paintgun."
|Low Pressure - Gas used to power a paintgun at pressures below 300
to 400 psi.
|LPR - "A Low Pressure Regulator - typically used to supply gas at around
100 psi at lower flow rates to drive low pressure pneumatics, like the
ram used to recock an Autococker."
|Mainspring - The spring which drives a hammer into a paintgun's valve.
|Marshall - A referee on a European paintball field.
|Mask - "In addition to directly protecting the eyes, paintball goggle
systems provide a mask with protection for the face, temple and ears. Face
protection is doubly important as it prevents a paintball from impacting
the cheek and blowing up into the eye."
|Max - "A perfect score in a tournament paintball game - Eliminating
all of the opposing players, pulling a flag first, hanging the flag, and
surviving with no players eliminated. In most tournament scoring, a max
is 100 points."
|Mechanical Bounce - Physical vibration when a paintgun fires which
causes it to fire additional shots after the one shot caused by a full
and distinct pull on the trigger.
|Milsim - "Paintball games and equipment meant to simulate military
action, from paintguns designed to look more like real firearms, to tactics
and rules to simulate injuries and complete specific missions."
|MPA - "Medium Pressure Air - Compressed air stored at 1,800 psi, MPA
was a stepping stone to the development of HPA, and is virtually nonexistent
in modern paintball."
|Mugging - "Aggressively eliminating a player - running up on them,
shooting them multiple times at close range."
|Mushroom - "A small, round topped inflatable bunker."
|"Nitrogen, nitro" - "Nitrogen was developed as a regulated power source
for paintball use in the early 1990s. Because compressed air consists of
more than 70 percent nitrogen, compressed nitrogen and compressed air can
be used interchangeably in HPA systems for paintball. Although nitrogen
is almost never used in modern paintball due to its higher cost and no
performance advantages compared to compressed air, many players mistakenly
call compressed air nitrogen, nitro or nitrous."
|Novice - The second skill/experience rank in tournament play - also
called Division II in some leagues.
|NPPL - National Professional Paintball League - corporation formed
in the early 1990s to sanction quality professional and amateur paintball
tournaments in the US. The original NPPL (often pronounced nipple) soon
lost its formal structure as member teams did not do the work necessary
to maintain the corporation. The individual promoters who later formed
the PSP continued to call their tournaments NPPL tournaments even after
the NPPL's corporation was dissolved by the state of New York for failure
to pay taxes in the late 1990s.
|"NPPL, Inc" - "A corporation created and owned by its president early
in the new millennium, to take the place of the original NPPL in sanctioning
quality professional and amateur paintball tournaments."
|Nubbin - "A ball detent made of a flexible piece of rubber like material,
or flexible wire."
|NXL - National X-Ball League - a professional level X-Ball league which
plays at PSP tournaments.
|On/Off - A less common valve used on CO2 tanks which can be turned
on or off by twisting a knob. Also an ASA equipped with on/off capability.
|One For One - "A method of issuing a penalty during tournament play,
that provides an immediate and balancing effect to the game. For example,
under most tournament rules, continue to play after being hit is punishable
by a one-for-one. The player who was hit will be removed from the game
because the hit eliminated them, and one additional player from their team
will be removed from the game as a penalty. More severe penalties include
a two for one, and a three for one, in which two or three players are removed
as a penalty for the infraction."
|Open Bolt - A paintgun design on which the breech is open while it
is at rest between shots. When rapid firing there is no difference between
open bolt and closed bolt operation.
|O-Ring - A ring shaped seal often made of rubber like materials.
|Over-shoot - "To shoot a player more times than is needed to eliminate
them from a game. Severe overshooting is usually penalized in tournament
play, and prohibited in recreational play."
|Paint Check - When a referee inspects a player to see of paintballs
have left paint on them.
|Paintball - "The projectile fired by paintball guns. A paintball consists
of an outer shell, and a thick liquid fill. According the ASTM specifications,
a paintball has a nominal diameter of 0.68 inches."
|Patent - "A method of legally protecting an invention. A design patent,
which lasts for 14 years from the date it is filed protects a specific
invention. A utility patent protects a method of how an invention or manufacturing
process works, and last for 20 years from the date it was filed. Obtaining
a patent involves research (usually with a patent attorney) to prove the
invention was not previously patented, and filing the claim. Owning a patent
is only half of the process. Actually enforcing the patent against someone
who violates it can cost from tens of thousands to literally millions of
dollars in legal fees. "
|PEG - PolyEtheleneGlycol - the chief thickening ingredient used in
|Penalty - "The punishment for breaking a rule. Early tournament rules
assessed penalty points, but modern rules use the one for one system for
on-field penalties because the effect is more immediate and designed to
balance and advantage gained by the breaking of the rule. Repeating score
formats like X-Ball use a penalty box, where the player who committed the
infraction must wait for a set amount of time, and that player's team must
compete with one less player on the field. "
